O.S. OS 120AX MAX w/E-5020 Silencer

The distinctive shape is hard to ignore, and with peak power of 3.1PS at 9000RPM, you can be sure that this engine loves big propellers! OS recognised that engines of this size are often used in scale models and have developed a silencer system that allows adaption to some of the 'tightest' installations. The carburettor features a neat needle valve that protects fingers while adjusting, yet is simple & accessible.
